1.The hydraulic drill rig,type MGY-80 mainly adopts fully hydraulic transmission method. The host machine is separated from the power station and the control panel and hence reducing the weight of the host machine.Equipped with hydraulic clamper and manual shackle which ease the dismantling works of the drill pipes.Detachable and convenient for shifting purpose. It has simple and compact structure, easy for operation.Large torque, wide range of rotational speed, large pulling force.

2、The drill rig,type MGY-90L has compact structure and equipped with crawler track which each the process of moving and be in place. Chassis, mast and other modulation mechanism are controlled hydraulically. Adjustment between 0.5-6 meters of various hole positions is achievable.Power head and guided rail are connected with new wear-resistant materials. Therefore, the guide rail wears little.2 rotating support and 3 modulation mechanism is designed prior to the rigidity of the drill rig is ensured. This is to allow wide range of angles adjustable for the drill rig and easier to align it with the hole positions. Radial drilling can reach 101.5°～+90° (the reference level is 0°) while the crawler track is fixed. The drill rig rotary angle on the track reaches -12°～+96°(0°when the rig arm and crawler track is in horizontal direction), the lateral drilling height reaches 480mm ～ 6300mm.

4、The drill rig,type MGY-100A adopts fully hydraulic power head structure. The engine is separated from the host machine to reduce its overall weight. Installation of diesel motor and electric motor is available to cater various needs of the customers.Adopt double power head structure and achieve multiple combinations to satisfy various drilling requirements.The drill rig adopts through-type down-the-hole full reverse circulation and partial reverse circulation technology for the first time.

5、The drill rig,type MGY-100BL uses large hole hydraulic chuck structure and installation of 6m drill pipe is available to improve the work efficiency.Its movements are handled by crawler track with the addition of 400mm up down moving adjustment of the drilling rig mast, the time taken for hole positioning can be reduce greatly.The drill rig has strong adaptability. As the drill rig equipped with large through-hole hydraulic chuck structure that has through-hole with Φ110mm diameter, no modification is needed on the power head to use together with single, double or triple drilling pipe. This satisfy the requirements of jet grouting, reverse circulation drilling and drilling for Φ108mm steel pipe roofing.

6、The gyrator of the drill rig,type MGY-135L is driven by double hydraulic motor. Fully hydraulic controlled, digital visualizing, flexible and convenient operation, easy for shifting and good maneuverability.Up-to-date changeable angle mechanism which makes the aligning works with the hole easier. The adjustment range is increased which helps to reduce the requirement on the working face.Equipped with specialized drilling pipe(drill pipe, casing, eccentric drill bit, etc.), high drilling efficiency and high quality.The drill rig main suitable for pit foundation supporting anchoring projects and rotary drilling constructions can be conducted through changing the jet grouting module.
